IPC: G11B7/135
Filed: 1983-07-26
Abstract: PURPOSE:To facilitate reproduction of signals by using an off-axis grating lens to produce a difference between the optical axis of the light incident on said grating lens from a light source and the optical axis of the light which is reflected from an information recording surface and transmitted through the grating lens. CONSTITUTION:The light beams 21 delivered from a light source 20 are turned into parallel luminous fluxes 24 through a collimating off-axis grating lens 23 and then made incident to a focusing off-axis grating lens 26. The primary diffracted light 27 forms a focal point 30 on an information recording surface 29, and the reflected light including information is sent again to the lens 26. While the zero-order transmitted light 31 goes back just as the transmitted light with an optical axis different from that of the flux 24. Then a focusing error, signal, a tracking error signal and a record information signal are detected out of the reflected light including the light 31 through a grating lens 32 for astigmatic optic and a photodetecting part including a 4-split photodiode 33. In such simple constitution, the signal can be easily reproduced.

Title: Fixing roller for electrophotography
Inventor: KATO TAKESHI
IPC: H05B3/00
Filed: 1993-06-07
Abstract: PURPOSE:To enable temperature control and maintain uniform temperature distribution by forming the inner diameter of a linear heat pipe larger than that of a heat radiation part, and providing a releasing layer around the heat radiation part. CONSTITUTION:The inner diameter of a heating part 1b of a linear heat pipe is formed larger than that of a heat radiation part 1a, and a releasing layer is installed around the heat radiation part 1a. The material of the heat pipe which constitutes a fixing roller is desirably copper or phosphor bronze. Though the inner diameter of the heating part 1b must be larger than that of the heat radiation part 1a, if it is too large, the amount of working liquid must be increased and, if it is too small, it exerts less effect. The fixing roller 1 thus constructed allows the working liquid to be accumulated easily at the heat radiation part 1b and, therefore, even if the heating part side of the fixing device is higher than the horizontal, the interior of the heating part 1b is not dried out and also the temperature control is not brought into inoperative condition.

Title: Method and device for reading latent image
Inventor: SHIBATA ATSUSHI
IPC: G02B26/10
Filed: 1989-05-31
Abstract: PURPOSE:To improve a reading speed by sequentially irradiating an accumulating phosphor sheet with beams, detecting fluorescence generated from the accumulating phosphor sheet and progressing the motion of rotational scanning in parallel with the accumulating phosphor sheet. CONSTITUTION:A laser light beam passes through respective optical fibers which constitute a light guide 3 to be divided into four beams, which exit from respective exiting ends 32-35. When the laser light beams exiting from the exiting ends 32-35 are cast to the part of the accumulating phosphor sheet 4 where a latent image is recorded, the fluorescence is generated. Then, it returns through the light guide 3, exits from an incident end 31 and is reflected by a dichroic mirror 2 to enter a detector 5 such as a photomultiplier, and it is converted into digital data to which specified processing is performed. The light guide 3 rotates with the center axis of the incident end 31 as the center of rotation while it moves in parallel along the center axis. Thus, pluralfold reading speed is obtained as compared with the case that the rotational scanning is performed with one stimulating light beam.

Abstract: PROBLEM TO BE SOLVED: To prevent the overdischarge of a battery and increase the usability of a rice cooker with the battery, even when stopping the feeding of a commercial power supply during a long term in the state that the battery is mounted on the rice boiler as it is, in the rice boiler having the battery as its backup power supply when the commercial power supply (AC 100V) is interrupted. SOLUTION: When the feeding of a commercial power supply is stopped, a power supply changeover switch 5 is changed over to the side of a battery 3 by the signal of a power supply changeover circuit 4 connected with a commercial power supply feeding section 2. Simultaneously, monitoring the voltage of the battery 3 by a microcomputer 9, when judging the value of the signal of a battery-voltage sensing circuit 6 as lower than a predetermined value, a switching element 7 is turned off to separate the battery 3 from a load 1. A power supply (VDD) of the microcomputer 9 is turned off too, and it is not recovered until the commercial power supply is turned on again. The power consumption of the battery 3 by its discharging is eliminated, when the battery 3 is in this state.
